IMPROVEMENT IN VARN-DRVING MACHINES.

Specification forming part of Letters Patent No. 190,609, dated May 8,1877; application filed February 12, 1677.

To all whom z't may concern ence being had to the accompanying drawing,

which forms part of this specification.

This invention relates to machines having a rotary motion for dryingyarns of all kinds, in hanks.

Heretofore it has been customary to simply hang the hanks indrying-rooms, and to admit into the latter highly-heated air,-for thepurpose of drying thebanks. This mode of drying is very objectionable,not only on account of the frequent conflagrations which occur by theuse of such highly-heated air, but also on account of the injurious.effects upon the yarns of said hot air. Thus, dyed yarns of the finestor most delicate tints are very injnriously affected, 'more especiallywhen yarns of different colors are dried togetherin the same room, whichcauses what is known to .dyers as breaking out. Also, yarns of lightcolors are apt to become spotted.

Qur invention has for its object the obviating of these objections, alsothe drying of the yarns in a more convenient, expeditious, andeconomical manner.

The invention consists in a revolving reel embracing various novelconstructions and combinations of parts, whereby the greatest facilityis afforded for hangin g up and arranging the hanks on the reel, and forremoval of the banks after the same have been dried, and for adaptingthe reel to hanks of difi'erent lengths, subject to variation of stretchalso,

for varying the exposure of the hanks throughout their length whilebeing'dried, to prevent unequal drying.

Although our machine may be worked in moderately-warm rooms to assistthe drying process, such is not absolutely necessary, and we altogetherdiscard the use of highly-heated air, for the reasons hereinbeforegiven.

Figure 1 represents a longitudinal vertical section of a yarn-dryingreel or machine constructed in accordance with our invention, and Fig. 2an end view of the same. Fig. 3 represents a longitudinal verticalsection of a modified construction of said machine, and Fig. 4 an endview thereof.

Referring, in the first instance, to the modification shown in Figs. 3and 4 of the drawing, by way of explaining certain features of theinvention which are common to the two constructions of the machine shownin Figs. 1, 2, and Figs. 3, 4, respectively, A A are opposite endframes, having upper bearings b b, in which the shaft B of the reel isrotated. Secured to this shaft, near its bearings, are the reel-heads,which are formed or provided with any number of radial arms, 0. Thesearms have longitudinal slots sin them, and are constructed on theirouter ends with bosses d, through which center-pins or bolts 6 areprojected to support or carry the longitudinal outer bars D of the reel.The center-pins c, on one end of the reel, are ad- 'justable throughtheir bosses d, but the center-pins e on the opposite end of the reelmay have a fixed relation in their bosses d.

The reel bars D are socketed at their ends to receive within them thepoints of opposite center-pins e. These bars, which are free to turn onthe center-pins, may be made of any suitable material, and be ofpolygonal or any other shape in their transverse section.

Within the slots .9 of the arms 0 are fitted sliding blocks E,adjustable Within and along the slotted arms,and secured therein bymeans of bolts, at any required distance from the center of the reel.These blocks are also formed with bosses d, and serve to carry, by meansof center-pins 0, similar to those hereinbcfore described, innerlongitudinal reelbars D The detachable connection of the severalreel-bars with the heads of the reel, by means of the center-pins 6,provides for the putt-ing on and removal ofthe hanks G ofyarn, which,when on the reel are carried, respectively, by

a pair of bars, consisting of one outer bar, D,

and one inner bar, D. The adjustment of the inner bars D along theslotted arms of the reel provides for adapting the latter to differentlengths of hanks, and for varying the stretch of the hanks.

After the reel has been thus loaded with the necessary number of hanksit is rotated at any desired velocity by shifting a drivingbelt, bymeans of a belt-shifter, f, from a loose pulley, g, onto a fast pulley,It, upon the shaft B of the reel, which latter may as readily have itsmotion arrested when required.

The radial arrangement of the hanks on the reel is favorable to thespeedy drying of them as the reel is rotated for the purpose, theairdraft produced being sufficient without heating the air.

Having thus described certain general features of the invention, by themodification shown in Figs. 3 and 4, which has been first selected inthis description on account of its greater simplicity, reference willnow be made to the more perfect, but complex, construction of themachine shown in Figs. 1 and 2, and in which- A A represent the endframes of the machine; B, its central shaft, which in this case servesto give rotary motion, by means of its fast pulley h, to a series ofvanes, H, constituting a rotary blower, which is concentric with thereel, and revolves in a reverse direction to the reel, and preferably ata higher velocity than it. Said blower may extend throughout the greaterlength of the reel, the heads of which latter are connected together bystays or bolts '8. and are supported by the shaft B in the bearings b,or by one or more sleeves passing through said bearin gs, only onesleeve, is, here being shown. This sleeve is projects beyond or to theoutside of the end frame A, which carries it, and serves to carry fastand loose pulleys lm for giving a slow rotary motion to the reel indirection of the arrow at, while the blower is rapidly rotated indirection of the arrow 3 and for arresting the motion of the reel whenrequired. The object of the blower is to urge an outward current of airthrough or over the hanks of yarn on the reel, and thereby to assist inthe drying of the hanks. Furthermore, the arms G of the reel in thisconstruction of the machine are represented as mainly radial withslotted oblique extensions 0 at their outer ends. The radial portions ofthese arms carry, by means of center pins 0 and spindles e on oppositeends of the machine, the inner set of reel-bars D, and the slottedextensions 0, which occupy an oblique position to the radial portions 0,serve to carry, by means of blocks E, adjustableinor out along saidextensions, and centerpins fitted through the blocks, the outer set ofreel-bars D, to provide, as in the modification hereinbefore described,for adapting the machine to different lengths and stretches of thehanks. This disposition of the inner and outer sets of reel-bars out ofthe same radial line allows of the hanks G being extended from the outerbars D of each arm to the inner bar D of the adjacent arm, as shown inFig. 2. This prevents that entanglement of light yarns in hanks, whichmight be occasioned by the sharp currents of air brought to bear on thehanks, supposing the latter to be in close proximity with each other.The hanks may be put in the reel, and be removed therefrom, ashereinbefore described; but the spindles e, which support the inner barsD at one end of the machine, have pinions M on their outer ends, and areso connected with the bars D as to be capable of turning the latter, yetpermitting of the displacement of the bars when required. By means ofthese pinions, which, as the reel is rotated, strike a stationary stop,N, the bars D will be slightly moved or rotated each revolution of thereel, thereby giving to the banks an intermittent motion, and so varyingthe surfaces of exposure of the hanks to the drying action of the reel,whereby unequal drying of them is prevented.

We claim- 1. In a machine for drying yarns in hanks, the combination, ina rotating reel, of an inner series of bars, D, and outer series of barsD, adjustable in relation with each other, and independently supportedby center-pins or spindles in the heads of the reel, to facilitate theplacing and removal of the hanks, substantially as specified.

2. The combination, with the radial arms 0, carrying the inner series ofreel-bars D, of the slotted, obliquely-arranged extensions 0, and theadjustable blocks E, carrying the outer series of reel-bars D,essentially as described.

3. The combination of a rotating fan or blower, H, with thereversely-rotating reel, having inner and outer series of reel-bars,substantially as specified.

4. The combination, in a rotating dryingreel, of an inner series ofreel-bars, with an outer series thereof, and means for intermittentlyrotating on their axes one of either series of said bars, essentially asand for the purpose herein set forth.

This specification signed by us this 21st day of November, 1876.
